ADA Geochemistry Building Blocks

Modular metadata schema components for the Astromat Data Archive (ADA), built using the OGC Building Blocks pattern.

Structure

geochemProperties (31 schema components)

Property building blocks that define ADA-specific metadata elements: file types, instrument details, technique-specific data structures, spatial registration, and more.

adaProfiles (36 resource type profiles)

Metadata profiles that compose property building blocks with CDIF base schemas:

• adaProduct — base ADA product profile (composes cdifCore + ADA properties)
• 35 technique profiles — technique-specific constraints (e.g., adaSEM, adaXRD, adaICPMS, adaTEM)

Cross-repo imports

This repository imports shared schema.org and CDIF property building blocks from metadataBuildingBlocks via the OGC Building Blocks import mechanism.

Tools

• tools/generate_profiles.py — generates technique-specific profile building blocks from configuration data
• tools/resolve_schema.py — Resolve all $ref into single resolvedSchema.json files
• tools/regenerate_schema_json.py — Generate *Schema.json from schema.yaml sources (YAML→JSON + ref rewrite)

resolve_schema.py and regenerate_schema_json.py are synced from the canonical copies in metadataBuildingBlocks/tools/. Do not edit locally — update the canonical copy and run python tools/sync_resolve_schema.py --apply from the metadataBuildingBlocks repo.
